' HAMILTON, OF SAME PLACE,

MEAT-CUTTEFlL Specification forming part of Letters Patent No. 60,984, dated November 14, 1865.

longitudinally. Fig. 3 is a View showing the construction of the shaft upon which the knives are fastened,with the helical flange attached. Fig.4 is a plan showing a cuttingknife detached.

Thenatu're of my invention consists in arranging a meat-cutter upon a vertical shaft, which is made to turn like a screw in con- -tinuationof the twist of the helical flange,

the knives being arranged successively nearer together, so that the operation of inincing the meat is perfected,and at the same time the chopped meat isby the operation of the screwformed cutters forced through the dischargepipe, the machine thus performing the double function of a sausagecutterand stufi'err To enable others skilled in the artto make and use my invention, I will proceed to describe its construction and operation.

In referring to the drawings, the same letters are employed in the different plans in connection with identical parts; 4

A is a metallic case inclosing the cutting apparatus, divided into two parts, A and A,

with latch and hinges toaiiord easy. access to the-knives,

. Bis afunnel shaped opening, through which the meat may be introduced in small pieces or strips. The lower edges of this month are made square, so as to shear the meat in comhination with the sharp edges K of the screw F.

, G is the crank, by which motion is communieated by the bevel-wheels D to the shaft 1. This shaft is made four-sided, the faces twisted like a screw, so as to continue the curvature of the propeller-shaped screw F, which. is placed upon the extremity of the shaft 1. The upper edges of this screw F are made sharp, so as, in. combination with the sharply-square edges of the funnel-shaped aperture B, to cut or shear the meat into small pieces, which are forced down by the action of the screw upon the knives G. The screw F is made of steel, or if made of cast-iron it has a steel knife attached to its upper extremity, by which the meat is'cut as it enters at B. These knives are thin plates of steel sharpened upon both edgesnvith a square hole, as shown in Fig. 4, of the size of the shaft 1.

These'knives are placed spirally upon the shaft separated by the washers E, which decrease in thickness from the top to the bottom, so that the meat as it passes down through the machine is constantly minced finer by'the' successivel'knives. The knives are sharpened on both edges, so that when one edge is dulled from use the knife may be reversed. \Vheu the meat has passed through the machine, it is discharged through the aperture L, which may be in the side, as represented, or in the bottom.

H are steel projections from the side of the case, between which the knives pass. These diminish in vertical diameter with the washers separating the knives.

Themode of operating the machinehas been indicated in the foregoing description.

The advantages claimed over other machines for a similar purpose consist in' its vertical arrangement, admitting of more convenient feeding, the meat need not be cut into small pieces, but may be fed in long strips, the first operation of cutting into suitable pieces being performed by the sharp edge K of the screw F. By reducing the distance between the knives G the operation of mine'ing the meat is more perfectly accomplished, and by the screw forni arrangement of the flange Fahd knives G upon the shaft the minced meat is forced from the discharge-pipe L, and in manufacturing sausage the skins being placed over this pipe will be filled and the meat minced by a single operation.

Having fully described my invention, what.

I claim as my invention, and seek to secure by Letters Patent, is-

1. The combination of the case A A. and vertical. shaft 1, substantially as described,and for the purposes specified.
